"It's a sunny morning", Xiao Z is lying in bed, watching the sky outside, "The weather in the South is good."
Small Z, which has become a system administrator of a unclear company.
This is a more complex company, and there are many small offices / branches around you. Through ISDN, DDN, microwave with the head office, visit the head office, or other companies shared.
The first thing to Xia Zi to the company every morning is to check a variety of logs. Look at the night, what happened, except for red wrong warning, and the wrong review with the lock, others all Brought over. "Nothing last night", there is a comfort in the small Z heart.
Pick up the tea cup on the table and started to prepare for a day in front of the water purifier. "The new MM of the front desk is good." Little Z colored a new girl in front of this reception.
"Dud ... beep ... beep ...", Xiao Z was shocked, the heart was secretly chanting, "Who will come on so early." Hurry picked up the cup of cool water rushed to the table, take A phone.
"Hello, XX Company." Little Z took up the first one of the customer service. "Hello, small z." "Yeah, you?" "I am a small S. My computer has a problem, I can't send and receive emails, I am very urgent, come over to help me see." "OK, I'll come over now."
S, a director of the company's C department, yesterday, the company gave him a computer.
Small Z came to the computer in front of the computer, the machinery has repeated the most action, start, runs, cmd.
In the DOS prompt that appears, the small z input: ping smtp.domain.com
"OK, let me see your IP configuration", so Xiao Z will then enter ipconfig / all
Thus, the mouse is another mad spot, control panel, network, and dial-up connection, local connection, attribute, TCP / IP, DNS. I am finally gotting. DOS command line Tip, enter: ping smtp.domain.com
"S, you can, look at it again, have any questions and give me another phone." Xiao Z left in the sacredness of S.
On the way back to your seat, I thought in the heart, "let me know which idiot, I must blainly."
Sit down, look at the surrounding colleagues, you have come, ask the little Y sitting next to, "Who is the computer of the C department?"
The little Y head did not lift a sentence. "Isn't you helping him?"
Little Z is full of fashion. . . -_- !!
"Right, Xiao S just called to come to you", Xiao Y is no secret and throws a sentence.
"What?" "Xiao Z wrinkled. "It seems that the machine is slow."
"Oh", the small Z is simulated a hoe, knocking in a small y, "I smash you."
(Background: Machine Configuration: IBM P4 1.8G / 128MB, 10 / 100MB Adaptive Net Card, the latest, best machine in the company.)
Small Z pick up the microphone, dialed S phone, "Hello, s?"
"Yeah, Xiao Z, come over and see, the new computer is so slow."
Little z a big head, thinking, "If you are slow, I don't know if anyone is slower."
But on your mouth, "Okay, I will come over now."
Sitting on the computer sitting in S, Xia Zi looks at the screen on the screen:
"Please wait, I am using computer settings ..."
After more than 10 minutes, the lovely welcome interface is finally coming.
"Is there no problem in the Internet? Receive email?" Small Z is quickly entered the administrator's username and password, while inquire about the problem with the network.
S pauses, "There seems no problem in other things. But this speed, it is difficult to endure, it is called how people use a computer."
Xiao Z started the number of work, start, running, cmd, only in the MSDOS window appearing, Xiao Z is only mechanical input DIR, but there is no problem in the head, "What is the reason?" ?where is the problem?"
Small Z's cerebral cortex kept movement, retrieving relevant information. One of the concepts caused his attention.
"Active Directory uses DNS as a positioning service to resolve the Active Directory domain, site, and service name into IP address."
"To log in to the Active Directory network, Active Directory customers must first place an Active Directory domain controller for their domain. To be positioned for the specified domain to the controller, the Active Directory customer wants to send DNS name queries to the following characteristics configuration DNS server:
1. Query Type: SRV (Service Location Resource Record) 2. Query Name: _LDap._tcp.domain_name
The response from the DNS server contains the DNS name of the domain controller and its IP address. From the domain controller IP address list, the client will try to contact each domain controller to ensure it run. The first domain controller of the response is a domain controller for the login process. "
Xiao Z clearly understands. It turns out that I have to log in, and the computer needs such a complex work. The client actually hit me to send an SRV type DNS query to _ldap._tcp.domain_name.
"OK, then I will add a DNS server IP." Hey, the keyboard mouse is a burst of mad. Control panel, network, and dial-up connection, local network, attribute, TCP / IP, small z is added to the IP address of the company's DNS server as a spare DNS server, and then turn over to S, "Okay, Restart. "
Start, shut down, restart.
The computer is still climbed with a snail, "Please wait ... I am using computer settings ..." and a long more than 10 minutes. Xiao Z didn't look back, it seems that I have seen the darkness of S.
The small Z is shouting in the heart, "Bill, your help has a problem !!"
(Bill, picked up the wolf tooth stick, gave a small z, "said, I will let your machine can't come!") Small Z has started a long search process again.
(The cerebral cortex: Boss, come to a little caffeine, otherwise I am excited)
"Halo, you also bully me, 5555555555", Xiao Z started the hard journey of his search.
Beginning, help, search, in "Word (W) you want to find" below, Xiao Z is old and realistic input "DNS", the mouse is listed "," Tian, find 390 topics. How can you! "
Then, select "Search the last result", "Enter the word (W)" to find the word (W) ", enter" Active Directory ", 125 results," Haha ", Xiao Z can't help but ecstatic, this less .
Xiao Z Click on the result of the query, a connection caused his attention - "The Working Principle of DNS Query" is once again realized, if the DNS server can't find the host information in your own server, you need to access the root server, then Look for the corresponding DNS server through the IP address returned by the root server, then find the relevant host information from the corresponding DNS server.
"OK", another burst of keyboard mouse mad thinking, Xiao Z poured a position in the order of the DNS server, "Let you get you? Xiaowei!"
Xiao Z returned to S, "I am restarted, there should be no problem." S nodded, "Okay, see."
The computer is finally launched by the best, but the troubles of DNS have not ended yet. S is done, no half a minute, the problem is coming, "Small Z, can not access the Internet and send and receive emails."
Xiao Z felt a buzzard of the cerebral cortex.
"Invert, what is it today? Windows98 is not used well, this Windows 2000 does not say management is convenient? The first place has so many questions? The dead Bill!"
(Bill, picked up the wolf tooth stick, gave a small Z two down, "said, I will let your company's machines can't come!")
[How is foreried out, and listen to the decomposition of the next time
